Sorry

Now that Microsoft has made the Windows 7 beta available for public download, many people are trying to figure out what's new and different. And many others not willing to risk their PCs by installing a beta OS are curious, too. (Thinking of installing the beta yourself? Use InfoWorld's free Windows Sentinel applet to see if it's compatible with Windows 7.)

Either way, I've put together 10 video tours of Windows 7, explaining what's added, remove, and changed in 10 areas that business users and IT care about. The short videos are quick lessons on what you can expect when Windows 7 ships later this year or early next year.
